Abstract
The utility model relates to a riveting pushing device which adopts the hydraulic oil cylinder pushing method and the compact pushing structure to eliminate a gap with a rivet. The riveting pushing device can bear repeated impact load, enhance technological feasibility of heading treatment, prevent the displacement and the looseness of the rivet, and enhance the service life of a component. The riveting pushing device is provided with a transverse guide block, a vertical locating column is arranged at the front end of the guide block, and the back end of the guide block is connected with a vertical pushing block; the pushing block is internally provided with a hydraulic oil cylinder, and the hydraulic oil cylinder is connected with a hydraulic pump by a pipeline which is arranged outside the pushing block.
Description
Technical field
The utility model relates to a kind ofly implements the holding device that uses when heading is handled to the rivet afterbody, belongs to the mechanical technology equipment.
Background technology
In the produced on-site process of rail vehicle, need assemble riveted joint to each member that constitutes car body at present, the rivet afterbody after the riveted joint need carry out heading to be handled, with the fastening effect of further reinforcement.
Existing heading technology needs two workmans to operate simultaneously usually, and a human jump bit impacts the rivet afterbody, and another people need look for other instruments that rivet head is held out against, and unloads out in case rivet oppositely moves back.
Owing to still do not have standard and special-purpose riveted joint holding device at present, therefore the heading processing procedure wastes time and energy, and usually because and have the gap between rivet and cause the displacement of rivet and get loose, thereby cause hidden danger safe in utilization for the riveted joint member, bring unfavorable factors such as member shortening in service life, maintenance cost raising.
The utility model content
Purpose of design of the present utility model, be to provide a kind of special-purpose riveted joint holding device to address the above problem and defective, adopt hydraulic jack to hold out against the structure that holds out against of method and compactness, with the gap between elimination and rivet, and can bear shock loading repeatedly, improve the technological feasibility that heading is handled, prevent the displacement of rivet and get loose, raising member service life.
For realizing above-mentioned purpose of design, described riveted joint holding device mainly has following structure:
One laterally steering piece is provided with a vertical reference column at the guide pad front end, connects a vertical withstanding tight block in the guide pad rear end;
Be provided with hydraulic jack in withstanding tight block inside, hydraulic jack is connected in hydraulic pump by the pipeline of withstanding tight block outside.
As above-mentioned overall plan structure, when carrying out the heading technological operation, the reference column of laterally steering piece front end carries the repeated stock load that the rivet afterbody is subjected in order to hold out against the head of rivet by the driving force that hydraulic pump is constantly imported to hydraulic jack.
When operating, only need hold out against rivet with guide pad, withstanding tight block are supported on any parts to get final product simultaneously.
For improving the mechanical property of whole holding device, described reference column and withstanding tight block be not on same vertical axis.
Described vertical reference column, its front end are provided with the indent locating slot that is used for ccontaining rivet head, so that rivet head is supported in the locating slot, eliminate and rivet between issuable gap, prevent that the rivet slippage from coming out.
As above content, described riveted joint holding device has the following advantages:
1, realized a kind of standard and special-purpose holding device, the heading process operations is provided, time saving and energy saving.
2, guarantee that rivet can not be subjected to displacement and get loose, eliminate the hidden danger safe in utilization of riveted joint member.
Description of drawings
Now in conjunction with the following drawings the utility model is described further
Fig. 1 is the schematic diagram that riveted joint holds out against operation;
Fig. 2 is the schematic diagram of described riveted joint holding device;
As depicted in figs. 1 and 2, riveted joint member 1, rivet 2, guide pad 3, reference column 31, locating slot 32, withstanding tight block 4, hydraulic jack 41, pipeline 42, hydraulic pump 43.
The specific embodiment
Embodiment 1, as depicted in figs. 1 and 2, and described riveted joint holding device, has a laterally steering piece 3, at guide pad 3 front ends one vertical reference column 31 is set, connects a vertical withstanding tight block 4 in guide pad 3 rear ends, reference column 31 and withstanding tight block 4 be not on same vertical axis.
Be provided with hydraulic jack 41 in withstanding tight block 4 inside, hydraulic jack 41 is connected in hydraulic pump 43 by the pipeline 42 of withstanding tight block 4 outsides.
Use above-mentioned riveted joint holding device, when rivet 2 afterbodys of fastening riveted joint member 1 are carried out heading technology, the reference column 31 of guide pad 3 front ends carries the repeated stock load that rivet 2 afterbodys are subjected in order to hold out against the head of rivet 2 by the driving force that hydraulic pump 43 is constantly imported to hydraulic jack 41.
Claims (3)
1, a kind of riveted joint holding device is characterized in that: have a laterally steering piece, at the guide pad front end one vertical reference column is set, connect a vertical withstanding tight block in the guide pad rear end;
